Therapeutic pillow

ABSTRACT

A therapeutic pillow includes a soft central section which received the back of one&#39;s head and pair of bolster segments for restraining the head from turning to either side. Underlying the central section is a dense buttress. The lateral ends of the buttress project upwardly and comprise a stiffening outer portion of each bolster. Both the central section and the buttress have a generally “U” shaped transverse cross section such that central section nests within the buttress when the composite pillow is assembled. A convex gradient neck extends forwardly from the central section and transitions to a convex cervical lordosis support at the central section. The buttress includes a central spherical cap depression. A portion of the central section occupies the depression to provide increased comfort for the occipital protuberance at the back of one&#39;s head.

BACKGROUND OF THE INVENTION 1. Field of the Invention

This invention relates generally to pillows and more particularly to pillows configured to maintain a sleeper in a supine orientation.

2. Antecedents of the Invention

A study by the American Society for Aesthetic Plastic Surgery (ASAPS) has revealed that sleeping on one's side or stomach contributes to the development of facial wrinkles. Facial wrinkles form in response to distortion created when the face is pressed against any sleep surface. The study, published in Aesthetic Surgery Journal, claims that sleeping supine, or on the back, is the best way to limit facial wrinkles, by relieving compression, tension and shear forces applied to the face during sleep.

Various other health benefits have been attributed to sleeping in a supine position. Such benefits include maintaining spine alignment, reducing chest compression, alleviating sinus conditions, alleviating acid reflux and reducing tension headaches.

While there have been attempts to provide pillows for maintaining a supine position, these have not met widespread acceptance, perhaps in part because the user felt constricted and they have not provided a comfortable head supporting surface for inducing sleep.

SUMMARY OF THE INVENTION

A composite therapeutic pillow includes a soft central section for receiving the back of one's head. Projecting upwardly at the lateral ends of the central section is a pair of bolster segments configured to restrain the head from turning to either side.

A firm or dense buttress underlies the central section. The buttress includes a pair of bolster stiffeners for engagement against the outer face of each bolster segment. Both the central section and the buttress have a generally “U” shaped transverse cross section such that central section nests within the bolster when the composite pillow is assembled. The buttress includes a central spherical cap depression occupied by portion of the central section to provide increased comfort for the occipital protuberance.

DESCRIPTION OF THE INVENTION

The present invention will now be described in detail with reference to the drawings, which are provided as illustrative examples of the invention so as to enable those skilled in the art to practice the invention. Notably, the figures and examples below are not meant to limit the scope of the present invention to a single embodiment, but other embodiments are possible by way of interchange of some or all of the described or illustrated elements.

Moreover, where certain elements of the present invention can be partially or fully implemented using known components, only those portions of such known components that are necessary for an understanding of the present invention will be described, and detailed descriptions of other portions of such known components will be omitted so as not to obscure the invention. In the present specification, an embodiment showing a singular component should not be considered limiting; rather, the invention is intended to encompass other embodiments including a plurality of the same component, and vice-versa, unless explicitly stated otherwise herein.

Applicant does not intend for any term in the specification or claims to be ascribed an uncommon or special meaning unless explicitly set forth as such. Further, the present invention encompasses present and future known equivalents to the known components referred to herein by way of illustration.

Referring now to the drawings the reference numeral 10 denotes generally to a therapeutic pillow constructed in accordance with and embodying the invention. The therapeutic pillow 10 includes front and rear parallel edges edge 11, 13 respectively, together with parallel right and left lateral edges, 16, 17, respectively which provide a generally rectangular foot print. The therapeutic pillow 10 may be formed of molded two piece construction including a central section 12 comprising a soft head support surface 15 and a pair of laterally spaced bolster segments 14A, 14B which extend upwardly.

With attention directed to FIGS. 1 and 2 , it should be noted that a ramp-like convex neck gradient 18 extends forwardly from the front edge 11 of the foot print and transitions toward the rear edge 13 to a convex surface having an apex 20 followed by a concave curvature 22 for cervical lordosis support. From the concave curvature 22, the head support surface 15 is generally planar as it progresses toward the rear edge 13.

Underlying the central section 12 and the neck gradient is a firm stiffening buttress 24, best depicted in FIGS. 3 and 4 . The buttress 24 comprises a central portion 26 which underlies the central section 12 and the neck gradient 18. The buttress includes a pair of upwardly projecting bolster stiffeners 28A, 28B which abut and stiffen the lateral bolsters segments 14A, 14B when the composite pillow is assembled. The central section 12 nests within the buttress 24 with both having a generally “U” shaped transverse cross section.

One should note that the central portion 26 of the buttress 24 includes a reduced thickness zone formed by a spherical cap depression 30. The spherical cap depression 30 is filled with a portion of the soft central section 12 whereby one's occipital protuberance will lie in registration with a relatively thick portion of the soft central section area and a reduced thickness area of the stiffer buttress.

Both the central section 12 and the buttress 24 can be each unitarily molded of a suitable foam material. The central section 12 and the buttress 24 can subsequently be bonded in nested configuration with chemical bonding or adhesives. Alternately, both the central section and the buttress may be molded in a single cavity or the central section may be molded over the buttress or the buttress may be molded over the central section.

The central section comprises foam which is less dense, i.e., softer and more compressible than the buttress foam, e.g. viscoelastic polyurethane foam.

By way of example only, the composite pillow 10 dimensioned for use by an adult may comprise an overall width of 51 cm, a depth of 30 cm, a buttress width of 15 cm, a buttress height of 13 cm, a thickness of 5 cm at the planar portion of head support surface 15, a width of 19 cm between the bolster segments 14A, 14B, a neck gradient extension of 6 cm and a neck gradient maximum width of 18 cm. The neck gradient 18 extends forwardly approximately 20% of the depth of the composite pillow, excluding the neck gradient 18. It is significant that the neck gradient maximum width is not greater than the distance between the bolster segments to assure alignment of the user's neck and head with the head support surface 15.

Thus it will be seen that there is provided a therapeutic pillow which achieves the various aspects, features and considerations of the present invention and which is well suited to meet the condition s of practical usage.
